CAR-AXLE BOX AND SADDLE.

To (LZZ whom it may concern.

Be it known that I, ELIEL L. Srruarxnox, of lVinthrop, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovementin Car-Axle Boxes and Saddles, of which the following is aspecification, reference being had to the accompanying drawings, formingpart thereof.

This invention relates to in'iprovements in car axle boxes and saddlestherefor.

The object of the invention is to so construct a car axle box and asaddle therefor that said parts may have a relative movement withoutundue increase in height.

Another object of the invention is to improve the general constructionof ear axle boxes and their saddles.

The invention consists in such peculiar features of construction andcombination of parts as shall hereinafter be more fully described andpointed out in the claims.

Figure 1, represents a partial sectional. view of the improved car axlebox and sad. dle taken on line 11 Fig. 2. Fig. 2, represents a similarview taken on line 22 Fig. 1.

Similar numbers of reference designate corresponding parts in bothfigures.

As shown in the drawing 5 represents a car axle box adapted to contain abearing of any well known construction adapted to re ceive a car axle.The upper portion or top of said box 5 has at its inner and outer endportions the turrets 6-6 having in their tops transversely extendingcompartments 77 the bottoms of which are shaped to form the oppositelyinclined ways 8 and 9. Between said turrets 6-6 the wall of box 5 isreduced in thickness to form the depression 10.

The saddle, indicated as a whole by the reference numeral 11, has theside bars 12 12 the lower surfaces 13-13 of which are furnished withcavities having the oppositely inclined surfaces 14E-15 while the endportions 1616 of said bars depend below such surfaces 1313 and areconnected in pairs by the transverse supporting ribs 17 and 18. Betweenthe cavities 77 of the turrets 66 and the corresponding cavities of theside bars 1212 are rolls 19-19 which support the saddle 11.

The ribs 17 and 18 form supports for the end portions a of the wellknown side frames 6 and the inner vertical surfaces of the sideSpecification of Letters Patent.

bars 1212 from side bearings for said ends a.

In use, movement of the saddle 1.1 in a direction transverse of the axesof the rolls 1)19 is resisted by the inclined surfaces 8 or 9 and 1415of the respective cavities and when strain, in such direction, on thesaddle ceases said rolls return to the positions shown in Fig. 1.

By this construction the end a of the side frame Z) is supported belowthe axes of the rolls 19-1$) and close to the bearing con tained in thebox 5. This feature being particularly desirable where the car axle c isjournaled in an antifriction or roller bearing contained within the box5 of which class of bearings one form is illustrated herein.

Having thus described my invention I claim as new and desire to secureby Letters Patent.

1. The combination with a car axle box having a pair of turretsfurnished with depressions, and rolls contained in said depressions of asaddle having inverted seats, to receive said rolls, and side bearingsand supports for side frames, said supports being below said lastmentioned cavities.

2. The combination with a car axle box having a pair of turrets and adepression be tween said turrets, and antifriction bearings carried bysaid turrets, of a saddle mounted on said bearings and having dependingmembers furnished with end frame supports the upper surfaces of whichare below the tops of said turrets.

3.. The combination with a car axle box having transverse ways, androlls rotatable in said ways, of a saddle having side bars mounted onsaid rolls and having depending ends connected in pairs by ribs wherebythe supporting surfaces of said ribs are below the axes of said rolls.

4;. The combination with a car axle box having turrets furnished withdepressions each having a pair of oppositely inclined surfaces, androlls in said depressions, of a saddle having cavities, to receive saidrolls, each having a pair of oppositely inclined surfaces, said saddlehaving side frame supports located below said cavities.
